This is the main info page for the tracks. As
well as Author name, length Zip Size, fast lap time and 8 lap race time
there are numbers for Flow and Difficulty which are derived from the
fast lap and race times as a %.
Flow - low % means a low average lap speed and a high % a high average
lap speed.
The Difficulty is the average difference of the 7 slower laps compared
to the fastest lap as a percentage.
Low % = an easy track High % means a more variable lap time / more
difficult track.
